Hi Torbiorn,

I think that My solution is good enough to fix this issue. The test result is positive. I modify some code on app_usbd_msc.c

I monitor SCSI command what happens when I eject disk from apple mac pc and If it is confirmed to be eject, I will turn off the power of USBD. If the user plugs and unplugs the USB cable again, it will return to its original state.

Thank you.

John.

Hi Torbjorn,

I use SPI not QSPI. Also, I find a way to fix this issue. But I need more test.

Thank you.

John.

Hi John

Are you using QSPI as well?

In not it is surely a different issue.

Whatever you find out, just let me know.

In the mean time please have a great weekend 🙂

Hi Torbjorn,

OK. I know.

Also,I think it is not same as my case from your link.

Maybe I try to fix it by myself.

Thank you.

John.

Hi John

I didn't realize a fix had been proposed in one of the older cases.

Did you try the fix proposed by art_art here to see if it fixes the issue for you?

Best regards

Hi John

I will contact the USB developers and ask for some input, if there is any workaround to this issue, and try to get back to you shortly.

[quote user="JohnCC"]Also, Are you sure the nRF Connect SDK doesn't have this problem?[/quote]

No, the problem might be there in the new SDK as well, but it is a lot easier to get things fixed in the new SDK since it is under active development. The new SDK also uses an open source model allowing anyone to suggest fixes to the libraries through Github issues and pull requests.

Hi,

I think 17.1.0 should be in the same situation.

In fact, our product is already in PVT stage. We can't change to the nRF Connect SDK.

Any suggestions? What should we modify it to solve this problem?

Also, Are you sure the nRF Connect SDK doesn't have this problem?

Thank you.

John.

Hi John

Did you test this with nRF5 SDK v17.1.0?

Unfortunately the nRF5 SDK is in maintenance mode only at this point, and is not receiving updates unless critical issues are found. The latest version is v17.1.0, and no more updates are planned beyond this.

The focus going forward is on the nRF Connect SDK, and it is recommended to switch to this SDK for all new designs.
